The Canton system restricted foreign trade in China by centralizing all commerce through the port of Guangzhou and imposing strict regulatory control over foreign merchants.1

Key limitations included:

Geographic Confinement: A 1757 imperial decree restricted all foreign maritime trade to Guangzhou, forcing merchants to operate from a small, designated riverbank area outside the city walls.1
Monopolistic Intermediaries: Trade was funneled through the cohong, a guild of authorized Chinese merchants who held a monopoly on foreign commerce and were held legally responsible for the conduct of foreign ships and personnel.1
Personal and Operational Restrictions: Foreigners faced severe constraints, including prohibitions on bringing women or firearms into the port, the exclusion of warships, and strict limitations on personal freedom.1
Legal and Financial Burdens: Merchants were subject to Chinese law, which lacked protections like the presumption of innocence, and were required to pay numerous arbitrary fees and exactions to local authorities.1

These restrictive conditions eventually fueled tensions, particularly as British traders sought to expand commerce beyond these narrow confines, leading to the Opium War and the system's eventual abolition.1
